The distribution and accumulation of coa are controlled by mud - diapir development 平面上具有分区分块性,纵向上co2分布具有分带分层性。
3.
For the exploration of gas hydrates , it is of great significance to study such geological structures as mud diapir and mud volcano 摘要在天然气水合物勘探中,海底的泥底辟和泥火山构造是重要的研究对象。
4.
When diapir fractures opened , entering of hot fluid into reservoirs may cause dissolution of carbonate minerals , and when diapir fractures closed , carbonate minerals precipitated in high temperature condition 底辟断裂开启时,深部富c02热流体进入储层,导致碳酸盐矿物溶解;通道闭合时,高温使碳酸盐矿物沉淀。
5.
In the high - resolution seismic profile , to directly identify the diapir is often difficult due to much similarity between diapir and the invasion of igneous rock , thus leading to multi - resolution 在高分辨率地震剖面解释中,直接识别泥底辟构造存在一定困难,主要因为泥底辟构造和火成岩侵入体在形态上十分相似,容易造成解释的多解性。

There are 3 types of reservoir for the continuing subsidence type basin , there are diapir reservoir , fault reservior , drape reservoir , and the source rock is apart from the reservoir , they are contact by fault ; and there are anticline reservoir , fault reservoir , incline reserve ir , mudstone reservoir under the denudation area , and the source rock is contact with the reservoir 以沉降为主要趋势的盆地的油气藏有底辟构造油气藏、断层油气藏、披覆构造油气藏,其烃源岩与油藏在空间上是分离的,并通过断层相连;剥蚀区以下的油气藏有背斜油气藏或断层油气藏、向斜油气藏及泥质岩油气藏,其烃源岩和油气藏可有密切的接触关系。

Surrounding these special problems met in gas hydrates exploration and through study of high - precision magnetic survey , the sea test by r / v haiyang 1y that is owned by guangzhou marine geological survey in dongsha area of the south china sea , systematical analysis of the test result and combination interpretation of magnetic survey with seismic profile , the authors successfully employ the method to recognize the truth or false of the diapir in seismic profile by integrating total field of high - precision marine magnetic measurement with its gradient change 本文就目前天然气水合物调查中存在的这些特殊技术问题,通过对海上高精度磁力测量技术方法研究、广州海洋地质调查局“海洋四号”船在南海北部东沙海域的海上试验、对试验结果的系统研究分析以及磁测和地震剖面两种手段的综合解释,成功地尝试了用高精度海洋磁测成果中的磁力总场和梯度变化特徵来识别水合物勘探中高分辨率地震剖面上的泥底辟构造真伪的技术方法。
