王家岗油田东部地区构造特征研究——以王146区块为例
Study on Structural Characteristics in the Eastern Area of Wangjiagang Oilfield—Taking Wang146 Block as an Example

王家岗油田位于东营凹陷南部缓坡带的东段，处于牛庄洼陷及其南斜坡的过渡带，其在沙四上亚段发育了大量滩坝砂岩储层，2010年7月在探明储量空白区完钻探井王146井，试油沙四纯下3砂组日油3.35吨，含水27%，打开该区滚动勘探新局面，在前人进行一系列研究基础上初步测算研究区纯下3砂组和纯上1砂组的储量规模近千万吨。因此，研究区油气成藏条件优越，勘探潜力大。本文在区域构造上着重对沙四上亚段断裂解释及断裂组合分析进行研究，为该区储层沉积微相研究及其他地质综合研究奠定了坚实的基础。
Wangjiagang Oilfield is located in the eastern section of the gentle slope zone in the southern part of Dongying Depression, in the transitional zone between Niuzhuang Depression and its southern slope. It has developed a large number of sandbar sandstone reservoirs in the upper sub-member of Sha-4. In July 2010, the exploration well Wang146 was drilled in the blank area of proven reserves, and the daily oil production of Sha-4 Pure Lower 3 Sand Formation was 3.35 tons, with a water content of 27%, opening up a new era of rolling exploration in the area. Based on a series of previous studies, the reserve scale of the Pure Lower 3 Sand Formation and Pure Upper 1 Sand Formation in the research area was preliminarily calculated to be nearly 10 million tons. Therefore, the study area has superior oil and gas reservoir conditions and great exploration potential. This article focuses on the interpretation of faults and the analysis of fault combinations in the upper sub-member of the Sha-4 reservoir in terms of regional structure, laying a solid foundation for the study of sedimentary microfacies and other geological comprehensive research in this area.
