【摘要】：随着全球油价低迷,致密油开发遇到严峻挑战,如何实现致密油有效经济开发是当前需要解决的问题。针对致密油开发"甜点"的品质问题,提出用甜度概念来表征致密油"甜点"的效益开发性。在致密油地质特征研究的基础上,根据致密油开发先导试验井的试采特征,选择单井综合成本、单井最终产油量和市场油价等参数建立致密油"甜点"甜度模型,制作了致密油"甜点"甜度评价图版;利用该方法评价了国内外6个典型致密油区"甜点"甜度,给出了致密油开发动用条件和优选依据。致密油"甜点"甜度评价对实现致密油效益开发具有重要意义。
[Abstract]:With the low global oil price, the development of dense oil is facing a severe challenge. How to realize the effective economic development of dense oil is a problem that needs to be solved at present. Based on the study of the geological characteristics of dense oil, the comprehensive cost of single well is selected according to the test and production characteristics of the pilot test well for the development of dense oil. The desserts sweet degree model of dense oil was established by single well final oil production and market oil price, and the desserts sweetness evaluation chart of dense oil was made, and the sweetness of desserts in 6 typical dense oil regions at home and abroad was evaluated by this method. The production conditions and optimal selection basis of dense oil are given. It is of great significance to evaluate the sweetness of dense oil "dessert" for realizing the benefit development of dense oil.
