Description
Technical field
The present invention relates to deep oil-gas reservoir probings and depleted gas reservoir to utilize technical field, more particularly to a kind of mud stone sample
Product utilize the device and method of landwaste remodeling mudstone sample.
Background technique
Mud shale wellbore stability be always perplex petroleum exploration and development a big difficulty problem, especially 20th century seven,
In the oil/gas drilling that the eighties carry out, since the understanding to mudstone caprock feature is insufficient, cause in drilling process due to hair
The complex accidents such as raw well collapses, leakage, bit freezing, the finishing drilling after invalid using various processing methods.But in recent years to energy need
The increase asked, the construction of underground natural gas storage enter the period of high speed development.Since underground natural gas storage tank is in peak regulation and guarantor
There is irreplaceable role, thus attention of the construction of underground natural gas storage tank by many countries, natural gas in barrier gas supply safety
The important set that the big state of production and consumption all utilizes the construction of underground natural gas storage tank as entire natural gas upper-lower operations unifying
Overall planning is carried out at part.Underground natural gas storage tank is that the natural gas that will be produced refills the underground space and a kind of people for being formed
Work gas field or gas reservoir.Underground natural gas storage tank is mainly built near downstream natural gas user city, and purposes is to ensure downstream
The peak regulation of user needs.
The underground natural gas storage tank starting of China is compared with the 1970s once carried out utilization gas reservoir in Daqing oil field and builds gas
The trial in library, and the underground natural gas storage tank that really begins one's study be in early 1990s, with the sweet peaceful Gas Fields in Shan discovery and
The construction of Shan capital natural gas transmission pipeline just begins one's study and builds underground natural gas storage tank to ensure Beijing, the metropolitan peace in Tianjin two
Full gas supply.
The underground natural gas storage tank majority of China's built in advance is to be stored up using the oil reservoir reconstruction of exhausted gas reservoir or exhaustion at underground at present
Air reservoir.It might have a bite or more mouthfuls of engineering rejection wells in exhausted oil-gas reservoir fault block, since the presence of these wells makes oil gas
The original leakproofness of the cap rock of hiding is destroyed.The formation of general oil-gas reservoir necessarily has storage cap rock well, and cap rock is mostly to seep
The extremely low mud stone of saturating rate, if the mud stone water-sensitive of cap rock is stronger, former wellbore may collapse after the more than ten years, make the sealing of reservoir
Property obtains certain recovery.If having restored its leakproofness by simulation test proof, it is likely that do not handle or reduction is handled
Workload and reach the seal request of gas storage.It uses manpower and material resources sparingly to reach, the purpose of save the cost.
