Background technology
Be used for offshore oil gas reservoir ore bed exploitation and the floating construction of producing or facility usually or use " dry type tree " (being installed in the oil recovery structure and the equipment at production riser system top) itself, perhaps with " dry type tree " with below riser systems or " wet-type christmas tree " of end, seabed combine.Dry type tree be pit shaft pass a standpipe and production tube system from the seabed, up to the production deck district of facility or the extension of raised platform around a well of floating.Described standpipe and production tube are suspended in the surface wellhead system, and the tensioned riser suspension supports this surface wellhead system on one.The purpose that should go up the tensioned riser suspension arrangement is a stayed surface well head load, and the relative motion between compensation surface wellhead and the unsteady facility.To supporting the unsteady facility of this riser systems, according to restriction, to its motion feature such as vertical fluctuating and inclination and the strict requirement of having waved feature-set to whole relative motion.
For finishing doing the drilling and well completion program of tree, currently there are several diverse ways.A kind of method is based on utilized portable offshore rig (MODU) preboring development well before nonvolatil unsteady facility is installed.The permanent facility of Bu Shuing will use less tieback and completion rig subsequently, so that carry out tieback on production riser, carry out last well completion work then, to begin oil recovery.
Alternatively, can use off set drilling, wherein MODU is very locating to carry out the oil-gas field development drilling well near a dried tree device (DTU) that carries out completion and production work.One fixing or slidably drill set be installed on the dried tree device, to carry out drilling and well completion program in succession.This drill set can be the complete rig that has support system, or supply vessel aided drilling (TAD) device.
Except off set drilling, above-mentioned current practice requires performing a programme in succession, wherein carries out the oil-gas field development drilling well earlier, does tree drilling well, completion then again.Allow to carry out simultaneously the off set drilling of oil-gas field development and completion/oil recovery, depend on utilizing MODU and DTU to carry out near operation advantageous environment condition.
Till now, can carry out the drilling and well completion of every mouthful of well in two to four months time frame because water depth and the oil reservoir degree of depth are enough shallow, therefore the operation of above-described order or environment strictness is from being that to finish the viewpoint of the enforcement time of first oil recovery and constant rate of production be acceptable.Along with the new huge energy reserve that confirms in super deepwater field (is 2000-3500 rice or darker as the depth of water) and in basic salt or the oil-gas reservoir below the salt sub-surface, the combination of the depth of water, the oil reservoir degree of depth, high pressure and high temperature and stratum challenge had a significant impact the drilling and well completion time of every mouthful of single well.Prospect pit may need six to nine months drilling time, and in the oil-gas field development scheme, drilling time may also need three to six months in addition, and also needs trimestral well completion design subsequently.Therefore, for the medium sized oil gas field in the super deepwater environment (for example Gulf of Mexico), the oil-gas field development scheme may need to consider whole oil-gas field development drilling program needs seven to nine years under the salt.
Therefore, the system and method for time that a kind of efficient of the oil-gas field development drilling and well completion/oil recovery that improves deep water offshore oil gas reservoir is provided in the prior art and therefore reduces the operation cost of these oil-gas reservoirs will be very favourable.Also very advantageously: improve this efficient, and reduce from starting oil-gas field development to the whole time interval that begins to recover the oil and spend, so that accessible littler than so far to the influence of ambient conditions.In addition, provide that a kind of like this to allow oil-gas field development work and well completion/production work side by side and still independently to carry out with the system and method for avoiding interfering with each other fully also be very favourable.
