摘要
渤中M构造覆盖型深层潜山作为勘探新区,受地质和工程因素的双重影响,潜山界面的准确卡取面临诸多难点,严重制约了地质资料录取和钻井工程安全.为了解决该类潜山界面卡取的难题,通过系统总结研究区潜山特征,以沉积背景作为地层对比的关键条件,形成了"地层层序整体认识+沉积特征横向对比+潜山界面微观解析"的三级控制体系,建立了一套适合覆盖型深层潜山界面的卡取方法.多口井的实钻验证表明,该潜山界面卡取方法有较好的应用效果,提供了可靠的数据支撑和评价依据,对该构造后续作业以及其他类似潜山构造的界面卡取产生积极影响,具有良好的推广价值.
Abstract
As a new area for exploration,the Bozhong M Structure covered deep buried hill is affected by geological and engineering factors.There are many difficulties in accurately identifying the buried hill interface,which seriously restrict the geological data acquisition and the safety of drilling projects.In order to solve this kind of the buried hill interface identification problem,the characteristics of buried hill in the study area are systematically summarized.Taking the sedimentary background as a critical condition for stratigraphic correlation,it has formed a three-level control system of"overall understanding of stratigraphic sequence+horizontal correlation of sedimentary characteristics+microscopic analysis of buried hill interface",and established a set of identification methods suitable for the interface of overburden deeply buried hill.The actual drilling verification of several wells shows that the buried hill interface identification method has a good application effect,provides reliable data support and evaluation basis,has a positive impact on the subsequent operation of the structure and the interface identification of other similar buried hill structures,and has good popularization value.
