Description
Technical field
The utility model relates to a kind of quarrying apparatus of offshore oil and gas field, particularly relates to output unit outside a kind of light-duty single point mooring (SPM).
Background technology
In recent years, in oil-gas exploration and development field, marginal field becomes one of focus of attention getting most of the attention.So-called marginal field, refer to those existing development technique with under economic condition because of relative poor exploitation of economy, still can reach through great efforts predetermined lowest economic index, thus the oil-gas field that can develop.Marginal field has following dual nature in definition: 1, under general condition, if adopt conventional means to drop into exploitation, its economic benefit is by the earnings target ground wire of very possible out of reach expection; 2, through great efforts, employ new technology, after new mode or nonconventional approaches, if it is dropped into exploitation, will probably reach the earnings target bottom line of expection again.That is to say, whether marginal field has the condition of economical and effective exploitation can be changed to a great extent mutually.Owing to being on the edge line of economic assessment, marginal feature is obvious, so this class oil-gas field is referred to as marginal field.Theoretically, the kind of marginal field is diversified, and the reason causing is also a lot, such as crude output, crude oil price, geological condition are complicated, reserves are little, crude oil property is poor, regional environment inclement condition of living in, petroleum contract is harsh, tax revenue is high.
Because the investment of offshore oil and gas field is high, running cost is high, therefore, under equal geologic condition, the marginal field that sea can not be developed cost-effectively compares land many.How to make this part subterranean resource develop cost-effectively, the in the situation that of verifying the obvious deficiency of oil resources in current soaring oil prices and the whole world, seem most important, therefore study the development technique of marginal field, to promoting the exploitation of China Seas marginal field to have very great meaning, it is the important sources that guarantees crude output sustainable growth.
