中原油田W220块由于构造极其复杂,储层物性变化大等原因,一直未能动用开发。W220断块区储层沉积条件复杂,纵横向变化大。主要目的层油砂体展布、控制因素与发育规律不甚明确,有利储层分布的主体位置难以把握。利用轻烃色谱分析技术对W220块储层进行含油性评价,为此后制定的后续投产方案及区块开发方案提供了重要依据。
Zhongyuan Oil Field W220 block due to the extremely complex structure, reservoir physical changes and other reasons, has not been able to use development. W220 fault block reservoir sedimentary conditions are complex, vertical and horizontal changes. The main purpose of the oil sand body distribution, control factors and the development of the law is not clear, the distribution of the main benefit of the location of the reservoir is difficult to grasp. The evaluation of the oil content of W220 block by using light hydrocarbon chromatographic analysis provides an important basis for the subsequent commissioning scheme and block development scheme developed thereafter.
