Abstract: Exploitation geophysics is a type of geophysical techniques with its application in exploitation phase of the oil field. By this technique the co-operation between the Key Laboratory of Petroleum Resources Research, Institute of Geology and Geophysics and Liaohe Oilfield has achieved preliminary results. It shows that oilfield exploitation can get good results in this way. So further co -operation between geophysicists and oilfield experts has a good future in exploitation of oilfield. We hope it will bring a new bright future for oilfield exploitation and offer a new techniques guarantee in finding new oil and gas resources for our country.

Celebrating the Physics in Geophysics  [PDF]

Abstract: As 2005, the International Year of Physics, comes to an end, two physicists working primarily in geophysical research reflect on how geophysics is not an applied physics. Although geophysics has certainly benefited from progress in physics and sometimes emulated the reductionist program of mainstream physics, it has also educated the physics community about some of the generic behaviors of strongly nonlinear systems. Dramatic examples are the insights we have gained into the ``emergent'' phenomena of chaos, cascading instabilities, turbulence, self-organization, fractal structure, power-law variability, anomalous scaling, threshold dynamics, creep, fracture, and so on. In all of these examples, relatively simple models have been able to explain the recurring features of apparently very complex signals and fields. It appears that the future of the intricate relation between physics and geophysics will be as exciting as its past has been characterized by a mutual fascination. Physics departments in our universities should capitalize on this trend to attract and retain young talent motivated to address problems that really matter for the future of the planet. A pressing topic with huge impact on populations and that is challenging enough for both physics and geophysics communities to work together like never before is the understanding and prediction of extreme events.
Stochastic resonance for exploration geophysics  [PDF]

Physics , 2008,
Abstract: Stochastic resonance (SR) is a phenomenon in which signal to noise (SN) ratio gets improved by noise addition rather than removal as envisaged classically. SR was first claimed in climatology a few decades ago and then in other disciplines as well. The same as it is observed in natural systems, SR is used also for allowable SN enhancements at will. Here I report a proof of principle that SR can be useful in exploration geophysics. For this I perform high frequency GaussVanicek variance spectral analyses (GVSA) of model traces characterized by varying levels of complexity, completeness and pollution. This demonstration justifies all further research on SR in applied geophysics, as energy demands and depletion of reachable supplies potentially make SR vital in a near future.

Abstract: The regolith-covered surfaces of asteroids preserve records of geophysical processes that have occurred both at their surfaces and sometimes also in their interiors. As a result of the unique micro-gravity environment that these bodies posses, a complex and varied geophysics has given birth to fascinating features that we are just now beginning to understand. The processes that formed such features were first hypothesised through detailed spacecraft observations and have been further studied using theoretical, numerical and experimental methods that often combine several scientific disciplines. These multiple approaches are now merging towards a further understanding of the geophysical states of the surfaces of asteroids. In this chapter we provide a concise summary of what the scientific community has learned so far about the surfaces of these small planetary bodies and the processes that have shaped them. We also discuss the state of the art in terms of experimental techniques and numerical simulations that are currently being used to investigate regolith processes occurring on small-body surfaces and that are contributing to the interpretation of observations and the design of future space missions.

Abstract: By chemical examination in laboratory and test in situ, we found that the CI^- content and SO^2-4 content are higher in Daqing oilfield, and the variation of the soil resistivity is bigger. The soils show strong corrosivity along longitudinal depth to steel equipments. By means of contact test with a reference electrode underground, we measured the distribution of casing protection potential along vertical depth. The results indicate that the casing protection potential curve is smooth, and the protection potential is lower than -850 mV. The casing protection current can polarize up to 10000 cm in depth. The bracelet anode and the casing can installed or repaired simultaneously in the fled with no additional troubles and cost to the conventional field operation, therefore, it is of applicable value.
Bilan et perspectives de l'injection de polymères sur le champ de Daqing Evaluation and Future of Polymer Injection in the Daqing Field  [cached]

Abstract: The Daqing field, discovered in 1959, is the largest oil field in the People's Republic of China, with original oil in place exceeding two billion tons. The heterogeneity of the reservoirs and the viscosity of the oil have resulted in a moderate displacement efficiency and in a high water-cut in the production. In order to increase the recovery, polymer injection was tested in two pilots between 1987 and 1992 after laboratory and reservoir studies. Both pilots proved highly successful and led to the decision to extend polymer injection to the whole field. This article presents the whole history of the Daqing Polymerflooding Project, from the preliminary studies to the extension.

Abstract: In view of the fact that corrosion induced leakage of casings gets much severe year by year of oil - water wells in Daqing oilfield, we put forward the anticorrosion methodology of sacrifice anodes, and the technology is the serial anodes are buried on the flank of the working casing of oil-water wells. Through simulation experiment in the laboratory, it follows that in case the water electric resistivity is appoximately egual to the cathode-anode area ratio, anodes should be buried underground with a depth of 3000 cm-5000 cm, the way of anodes combination is connection in series-parallel, and it would come into being the bigger electric current output and the good potential distribution. The suitable spacing between of anode and cathode ranges around 900 cm.

Abstract: In the process of oil displacement of ASP (Alkali/ Surfactant/Polymer) flooding , when Alkali interacts with the fluid and minerals of the reservoir, the alkali is subject to be consumed. The consumption regularity is the key factor affecting ASP ingredient, injection plan, scaling regularity for production wells and oil displacement effectiveness. Therefore to study the alkali consumption is of great significance in guiding ASP ingredient, injection project design, and the analysis for oil displacement mechanism. In this paper, aiming at the main components of minerals in the reservoir in Daqing Oilfield, the laboratory study on static alkali consumption for five kinds of minerals (kaolinite, grundite, chlorite, feldspar and quartz) in ASP system and single component NaOH solution are done respectively. The alkali consumption regularities for five kinds of minerals in ASP and single component NaOH solution are concluded. The research indicates that the amount of alkali consumption for kaolinite, grundite, chlorite, feldspar and quartz is changing from larger to less accordingly, but is mainly caused by clay minerals; the average alkali consumption is 18.3% higher than that by matrix minerals. In single component NaOH solution, the alkali consumption styles of clay minerals and the matrix minerals take the chemical reaction as the lead, and the physical adsorption as the second. In ASP system solution, the alkali consumption style of clay minerals, takes the physical adsorption as the lead, and of matrix minerals takes the chemical reaction as the lead. In ASP solution, compared with single component solution, polymer and surfactant have the functions of restraint to alkali consumption in minerals of the reservoir, and the amount of alkali consumption decreases evidently.
