摘要:
车排子油田A井区石炭系火山岩储集层属于孔隙-裂缝型双重介质,其油气成藏和产能受断裂、岩性、岩相、孔隙和裂缝等多重因素的影响,成藏规律复杂,产量差异大。以开发产能为主导,综合利用地质、测井、分析化验、地震等资料,分析了岩性、岩相、基质物性和裂缝等储集层因素和产能的配置关系,明确了石炭系火山岩油藏的油气生产特征,结果认为在靠近火山口爆发通道的爆发相和溢流相等优势岩相内,发育火山角砾岩和气孔状玄武岩等有利岩性,对应的基质物性好、裂缝发育,高产井分布多、产量高,同时在测井曲线上表现为自然电位测井曲线负异常和电阻率—密度测井曲线具一定叠合面积的电性特征。结合产能主控因素和开发动态产量,在平面上划分出3类储集层有利区,Ⅰ类储集层性能最优。由此,结合测井曲线特征,提出对9口老井进行恢复试油建议,并建议针对C3和C4岩体新部署11口开发评价井。
Abstract:
The Carboniferous volcanic rocks in Wellblock A of Chepaizi oilfiled belong to the pore-fracture dual-media reservoirs, in which hydrocarbon accumulation and well productivity are affected by multiple factors including fault, lithology, lithofacies, porosity and fracture, leading to the complex hydrocarbon accumulation law and unstable well productivity. Based on the data of geology, well logging, lab analysis and seismic interpretation, the paper analyzes the configuration relationship between the productivity and reservoir factors such as lithology, lithofacies, matrix physical property and fracture, and confirms the hydrocarbon production characteristics of the Carboniferous volcanic reservoir. The results show that both the explosive facies and effusive facies near the volcanic vent are the predominant lithofacies where volcanic breccia and stomatal basalt are the favorable lithologies with good matrix physical properties and developed fractures. In the wellblock there are many high-yield wells whose logging curves are characterized by both negative anomaly in SP and a certain overlapping area between Rt and DEN. Considering well productivity and its controlling factors, three types of favorable reservoirs are classified in the plane and the type I is the best. On the basis of the above, combined with the logging curve characteristics, 9 existing wells are proposed to carry out formation test and 11 new development wells are suggested to be deployed on the C3 and C4 volcanic rock mass
